UTG has Q[img]/images/graemlins/spade.gif[/img]Q[img]/images/graemlins/diamond.gif[/img] btw.

I'm mostly worried about UTG+1. Havent seen him do much weird stuff. But what could his minraise mean here?

Who folds here?
Who raises here?
I most def. dont like a call here, because youre committing yourself anyway.
